The water tube I8 is provided with the port 30Acommunicating with said water space 28. Gaskets '3I-3I are disposed uponthe opposite sides of said ribs 21-21 for cooperation with said ribs.Disposed upon the lower side of the lower gasket 3| as the parts areviewed in Figure 1 is the sleeve member 32, which is illustrated asbeing of I- shaped contour in cross section. The web of the sleevemember 32 is provided with a plurality of ports 33-33. the port 34disposed in proximity to the web portion of the sleeve member 32. Thebearing 20 is provided with the port 34A through whichv communication ishad to the water pipe-`34B. Disposed below the sleeve member 32 is thegasket 35. Glands 36-'36 serve to hold the gaskets 3I-3I and 35incompressed condition whereby escape of water from within the bearing 20is prevented. 'Ihe pipe I5 and the water tubes I1 and I8 are closed `at`their extremities adjacent to the turning member vIIIA.

In order that'the `soot blower comprising the pipeIS and the ytubes I1and I8 may be turned within the bearings I9 and-20, the presentinvention contemplates a structure in which the` assembly of said pipe'I5 and tubes I1 `and I8 is built up into cylindrical form at the regionsthereof journaled `within said bearings I9 Vand 20. The cross: sectionalviews appearing in Figures 2, 3 and 4 illustrate the fact that the tubesYI1 and I 9 are joined to the pipe I5 both physically andthermallybymeans of the metallic deposits indicated by the numerals31-31. These deposits 3.1-321 are vrepresented by VrelativelyV densecross sectioning.

The material for forming the cylindrical contour of the soot blower isindicated by the numerals 38--38, it being noted that access to theports 24-42'4 .isnot interfered with,k By reason of the I-shaped contourof the sleeve member 32, access between the tube I1 and the water pipe34B is "insured Iregardless of variations within limits Vin the degreeof compression of the gasket 35 and the gasket 3| adjacent thereto. In.other Words, the I-*shaped member 32 may vary considerably in its axialposition without interfering with access :between the water pipe 34B andWater tube I1. The illustrated construction is cheap .and obviates thenecessity for niceties in manufacture.

In 'the operation of the embodiment of the `invention illustrated in.Figures l to 4 inclusive, steam for Vsoot blowing purposes is admittedthrough .the pipe`23 and enters the Ypipe I5 'through the lport 24. Thesteam jets ypass out through the apertures I 6I6. may be turned by meansof the turning .member I8A so that said jets may be directed in anydesired direction radiating from the axis Yof the tube I 5.

Water for` coolingpurposes may be admitted through the pipe 34B and willVpass through one of the ports 33 into the annularspace within thev webof the s'leevemember 32. From saidannular space .the cooling water willenter the port V34 in `heitube I1`andpass along :said tube to the otherextremity thereof Vinto the tube I8. The Water will be discharged fromthe tube I8 through the port 30A-into the. water space 28 and throughthe pipe 30.

Figures 8, 9, 10 and 11 illustrate slightly differ.- Y

ent constructions of the assembly of pipe I5 and tubes I1 vand I8 in theregions thereof upwardly of the bearing 2.0 asthe parts are Viewed inFig- The water tube I1 is provided withf 1 The soot blowerV the tube I5is swedged slightly inwardly at the regions adjacent to the tubes I1 andyI8 whereby to increase the area of physical contact between the tubesI1 and I8 and said pipe I6. The deposits of welded metal 31 serves, inthe manner previously discussed, to connect the tubes I1 and I8 bothphysically and thermally to the pipe I5.

Figure 10 illustrates a construction in which the tubes I1 and I8 areheld in position relative to .thepipe I5 by means of the angle members39, which are bowed to conform to the contour of the tubes I1 and I8 andwhich are united to the pipe I5 vby lmeans of the deposits of Welded.metal 40-40. Y Figure 11 is similar to the construction shown in .Figurel0 but shows the pipe-I5swedged inwardly to conform to the adjacentcontours of the tubes `I1 .and I8, whereby to increase the area. ofcontact between the pipe `I 5 and the tubes I1'and I8.

Figures 5, 6, 7, `12 and 13k illustrate a construction in which fourtubes are provided for carrying cooling water in thermal communicationwith the pipe I5. The four tubes for cooling water are indicated by thenumerals 4I, 42, 43 and ,44. As shown in Figure 5,7said tubes 4I, 42, 43and 44 are disposed in position symmetrical with each other and with theaxis of the pipe I5 and arev so disposed circumferentially of thepipevI5 that they leave the ports 24-24 unobstructed. By reference toFigure 7 ity will be noted that the pipes 4I and 44 are provided withthe ports 45 and 46 communicating with the annular space within the webof the sleeve member 32, whereby cooling water enter-ingy from thecooling pipe 34B may, through the ports 33-33, have access to said tubes4I and 44. The water will ow upwardly through .said tubes 4I .and 44 andwill ow downwardly through the tubes 43 and 42, respectively. Byreference to Figure V6 V:it will be noted that said tubes 4'3 and 42 areprovided Withthe the tubes 4 I, 42, 43 and 44 tothe pipe' I 5 by means Kof angle members, after the fashion `illustrated in Figures l10 and 11,respectively, 'in whichjan Y angle .member 39 is provided for -eachfofthe cool-V ing tubes, and has each of .its edge' portions firmly united4to the .pipe I5 by means of depositsV of weldedmaterial, indicated bythenumerals 40- 40. s y
